Instrument Name: Anemometer
This instrument is a round brass dial supported on three glass legs and affixed to a black metal base. The face of the dial is set behind glass and consists of four separate dials: one large dial that takes up the entire disk, and three smaller dials set inside it. The large dial has a scale from 0-100 at ten-unit intervals, each of which itself is divided into tenths. The first of the smaller dials is labelled “100″; the second is labelled “1000″; and the third is labelled “10000.” Each is divided into 10 intervals.
A round metal frame with fan blades is affixed to the brass dial at a 90-degree angle. The centre of the fan is connected directly to the brass dial with a small metal rod. On the side of the dial is a single brass button and a brass switch.
This instrument is contained in a leather case with a leather handle. Also in the case is a brass and metal mount which screws into the base and allows the dial to be set on a rod. The leather case is closed with a metal button.
